APPARATUS FOR DRAWING OFF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 688,586, dated December10, 1901. Application led August Z6, 1901. Serial No. 73,250. (Nomodel.)

To all whom may con/067%:

Beit known that I, ALFRED BRAKE, a subject of the King of Great Britainand Ireland, residing at Clapham, London, England, have inventedImprovements in Apparatus for Drawing Off Liquids, of which thefollowing is a specification.

This invention consists of improvements in that kind of apparatus fordrawing off liquids in which a vessel, commonly called the intermediatevessel, is normally in communication with the liquid-storing vessel, sothat it will stand charged with liquid ready to be drawn 0E; and it hasspecial reference to apparatus for drawing off lager-beer'and other likeliquids highly charged with gas under pressure and hereinafter referredto as beer, wherein theintermediate vessel, which serves as a frothingand settling chamber, is normally in open communication with theliquidsupply pipeor vessel, is provided with a normally closedliquid-discharge pipe or passage leading from its lower end, and isadapted to have its upper part, which is normally disconnected from theexternal atmosphere, placed 'in communication with such atmosphere, whenrequired, so as to allow of gas under pressure therein being released,when desired, without closing the liquid-inlet or opening theliquid-outlet. Apparatus of this kind is described in the specificationof my United States Patent No. 673,532.

My presentinvention has for its object to enable lager-beer and otherfrothy liquids (hereinafter referred to as beer) charged with gas underpressure to be drawn ed either with very little froth or with a creamyhead of froth of any desireddepth. j

The invention consists, for this purpose, in an improved constructionot' draw-olf apparatus wherein the liquid-inlet of the intermediatevessel or frothing chamberis in constant communication with theliquid-supply pipe or vessel and is made of smaller cross-sectionalranged as to placethe top of the intermediate vessel only in temporarycommunication with the externalv atmospherewhen operating the apparatusfor the purpose of drawing off its contents or a portion thereof, sothat upon A operating the apparatus for the purpose just mentioned thegas-outlet will be first opened to release the gas-pressure and thenclosed, and the beer-outlet will be opened and beer allowed to run outof the intermediate vessel faster than fresh beer will4 run into it, andWithout any admission of air to such vessel, with the result that beercan be drawn off in advantageous manner and with very little froth. y

The invention also consists in providing in connection with the saidintermediate vessel means whereby any desired quantity offrothy beer canbe drawn oiii' into a glass or other receptacle, either after or beforethe main quantityof beer has been drawn off,with very little froth, soas to produce the desired creamy head of froth.

The invention also consists in various other novel features ofconstruction and in certain combinations and arrangements of parts, allas hereinafter more fully described, and specifically pointed out in theclaims.

In the accompanying illustrative drawings, Figure l shows in verticalsection one construction of draw-off apparatus constructed according tothis invention, and whereby beer can bedrawn off with very little froth.2, 3, i, and 5 are sections onthe line A A of Fig. l, showing the plugof a cock forming part of that apparatus in four different positions.Fig. 6 is a vertical section showing drawingot`f apparatus like thatillustrated in Fig. l, but adapted to admitof a small quantity of frothybeer being drawn od direct from the beer-supply pipe. Fig. 7 is across-section on the line B B of Fig. 6. Figs. 8 and 9 arecross-sections on the line C C of Fig. 6, showing the plug of thedraw-off cock in two different positions. Fig. lOris a similar View toFigs. l and 6, showinga modified construction for enabling a smallquantity of frothy beer to be drawn od.

In the arrangement shown in Figs. l to 5, inclusive, the intermediatevessel a, which Figs.

may be of pewter, glass, or other suitable ma- IOO .smaller than theliquid-outlet.

, below the normal level of the liquid in the vessel andterminates neartotheinnersurface thereof. At its lower end the said vessel a isprovided with a beer-outlet pipe (Zand also with a gas-outlet pipe e,the top of Which terminates within and near to the top of the saidvessel, and the lower end of which terminates in a passage e', arrangednear to a beer-outlet passage d', communicating with the pipe d. Thebeer and gas outlet passages d and e are controlled by a cock or faucetcomprising a plugf and a case g, which in the example forms part of atubular device h, in which the said beer and gas passages d and e' areformed and which is provided with a socket ,vin which the lower end ofthe intermediate Vessel ais secured in a fluid-tight manner by a dividedscrew-ring 7c and a packing-ring lm. The pipes d and e are secured inthe bottom of the socket t', so as t-o be in communication with thepassages d and e', respectively. The passages d' ande terminate in portsd2 and e2 within the case g, and the plugf is formed with ports f andf2. These ports d2, c2, f', andf2 are so relatively arranged, as shown,that normally (see Figs. 1 and 2) the beer and gas outlet passages d andc' are both closed and that upon turning the plug fin the direction ofthearrow l by the handle t the gasoutlet passage e will be first openedthrough the port f', Fig. 3, and then closed, Fig. ft, after which thebeer-outlet passage d will be opened through the port f2, Fig', and uponturning the plug in the opposite direction backinto its originalposition the beer-outlet passage d will be first closed and then thegasoutlet passage e will be again momentarily y opened and closed. Theintermediate vessel a may, as shown,conveniently resemble a bottle inshape and be held in an inverted. and inclined position within a box n,adapted to contain ice, the neck of the bottle-shaped vessel beingcarried by the tubular device h, which extends through a hole in thelower portion of the said box, in which it is secured by a screw-ring 0Vor other suitable means and a packing-ring o.

By the construction described the intermediate vessela will normallystand nearly filled with beer charged with carbon dioxid under pressure,and above it, within the upper part-A and upon the liquid-outlet beingafterward opened while the gas-exit opening is closed the beer will bedischarged by gravity, aided by the gas-pressure still existing in thevessel and the intlowing beer, the beer iowing out into a receptacle ina smooth steady stream with the production of very little froth. Duringthe drawing olf a fresh quantity of beer will enter the vessel, but at aslower rate than the issuing beer on account of the cross-sectional areaof the inlet being less than that of the outlet, this iniiow continuingafter the liquid-outlet `has been closed and until the level of theliquid rises to the normal height and the gas-pressure in the vesselbalauces the pressure under which the beer is supplied. To obtain thebest results,

a short interval should elapse between sucv cessive drawing-offoperations to allow time for froth producedin the vessel during theiniiow of a fresh quantity of beer to settle. For this purpose, where itis desired to draw off lager or like beer frequently, it is convenientto use several vessels, arranged side by side,and to draw off .beer fromeach of them in succession.

In some'cases, instead of drawing off beer of the lkind referred to intotumblers or other receptacles, so that there shall be very little frothQn the surface of the drawn-ofi:` beer, as hereinbefore described, it isdesired that the surface of the beer shall be covered with a creamy headof froth of, say, about twelve millimeters in depth. To enable thisresult to be attained, the drawing-off apparatus is constructed in sucha way that after any desired quantity of the beer has been drawn offwith very little froth from the intermediate vessel the beer-outlet canbe placed in direct communication .with the rbeer-supply pipe or vesselor with the intermediate vessel with out releasing the gas-pressure fromsuch vessel, so that the necessary small quantity of frothy beer can bedrawn off to produce the desired effect. Usually the movable handle orequivalent (hereinafter called the handle employed for effecting thedrawing off of beer from the intermediate vessel will be employed foropening the outlet for frothy beer. For this purpose the handle may beso arranged that when moved in one direction it will effect the releaseof gas under pressure from the top of the intermediate vessel which isin communication with the beer-supply Ypipe or vessel, as before, andwill eect the opening of the beer-outlet from the said vessel, and uponbeing moved into another position it will open the passage for thesupply of frothy beer.

As will be obvious, draw-off apparatus of the kind herein referred tocan be constructed in various forms to give the above-mentioned result.purpose in Figs. 6 to 9, inclusive, the intermediate vessel a iscarriedby va tubular device h, formed, as before, with beer and gas IOO IIO

outlet passages d and e', that are respectively in communication withthe beer and .gas pipes d and e and are controlled by the plug f of acock or faucet constructed and operating as hereinbefore described withreference to the arrangement shown in Fig. 1. The tubular device h is,however, formed with a third passage t, that is connected by a suitableby-pass pipe u direct to the liquidsupply pipe c and termi-natos in aport fu in the valve-case g, and the plug f is formed with a third portf3, so arranged in relation to the other two ports f' and f2 that whenthe plug is turned backward by its handle Z beyond its normal position(shown in Fig. 8) and into the position shown in Fig. 9 it will open thethird porto and the secondary pipe t and allow frothy beer to be drawnoff, for the purpose set forth. Z is a spring by which the handle Z willwhen released be automatically returned to its normal position, Fig..

8, in which each of the ports d2, e2, and o is closed.

As the beer standing in the intermediate vessel would issue therefrom ina frothy condition if the excess of gas-pressure in the top of thevessel were not released previous to the drawing off, it will be obviousthat a small portion of such frothy beer may be drawn off for producingthe desired amount of head on the drawn-off beer having very littlehead. For this purpose the plug f may, as shown in Fig. 10, be formed,in addition to the ports f and f2, with a third port f3, so arrangedthat after beer has been drawn off with little or no head and the plughas been returned to its normal position and the vessel a allowed tobecome recharged with a fresh quantity of frothy beer, as hereinbeforedescribed, a small quantity of such beer can be drawn off by turning theplug backward to a small extent beyond its normal position, so as toagain open the liquid-outlet d', but this time through the port f3 andwithout releasing the excess of gas-pressure from the top of thevessel., so that frothy beer will then be drawn olf. With thearrangements shown in Figs. 6 to l0, inclusive, the desired quantity offrothy beer can, if desired, be first drawn off by moving the handlebackward and then the desired quantity of beer with very little frothcan be drawn off by moving the handle forward. Also with thearrangements shown in Figs. 6 to 1U, inclusive, the cock can be used foropening the intermediate vessel a for drawing off beer without openingthe gas-exit port e2 at all when for any reason the pressure of the gasin the said vessel falls so low that it need not be reduced beforeopening the beer-exit port d2.

It will be evident that va rions changes could be made in the details ofconstruction of my apparatus without departing from the spirit and scopeof the invention so long as the relative arrangements of parts shown inthe drawings or the mode of operation described in the specification ispreserved.
